Description

 TECHNICAL CHARACTERISTICS:

The protection relays used in the Retrofit have extensive protection features and are fully integrated into SCADA systems under multiple protocols and communication ports, as well as facilitating telecontrol and remote management of equipment.

Las soluciones de retrofit tecnológico de ATA Electric para reconectadores GVR Whipp & Bourne han sido aprobadas directamente por el fabricante, garantizando de esta manera la confiabilidad de esta solución.

 

 ADVANTAGES:

  • Power Switches Refurbishment with an investment of up to 50% of the value of the equipment for the different voltage levels of 15kV, 27kV and 38kV.
  • Technological update of the control box with requirements that meet the automation needs of the Distribution Systems.
  • There are no costs associated with the de-energization nor service interruption of the power supply since our solution enables the upgrade even with the equipment in service.
  • Complete integration to SCADA systems and Remote Management through ports and using the communication protocols most used in the electrical industry: IEC 61850, IEC 60870-5-101 / 104, Modbus, DNP 3.0.

RELE FTU – R200

RETROFIT FOR GVR WHIPP & BOURNE RECLOSERS

 

Type of Retrofit Type of Relay Restrictions
GVR PolarR 751A modifying GVR Bulkhead and including Short-Circuitable Terminal Blocks. Non-removable Umbilical (supply or shipment)

No SF6 measurement.

When the configuration of the Bulkhead is needed, the GVR must be sent to our Laboratory.

The Serial Number of the GVR is required.

GVR Pplus 751A (The option of Voltage measurement by CVTs is lost) Requires sending the Serial Number of the GVR
GVR 351P 751A (The option of Voltage measurement by CVTs is lost) Requires sending the Serial Number of the GVR
